We usually buy ready made smoke generators - Action Electronic, Hunter systems, Graupner, Robbe (heated coil types) or the Ex JJC Water vapor unit.... which one do you have?

I am a cheapskate, so I make my own smoke generators.  Hannah has one fitted in her destroyer and it looks effective and they only cost a few pounds....

I REALLY don't understand why anyone would want to buy a product which was material in closing down a business because of quality issues. Have I missed something here - Russian Roulette, maybe? If I had a quid for every phone call I've received about the range of JJC units and their attendant problems then I'd be cruising in the West Indies now.
 
FYI I gather that Harbor Models of California are about to introduce a unit which is similar to ***, save that it's oil-based and costs $100. There is also a German company who offer a similar unit for 120 Euros..............and no; we've  no intention of developing one.

Suit yourselves.

Hi Dan, here goes......
All you need is a small reservoir, a small computer chip cooling fan, some NI-Chrome wire (heating element out of an old hair dryer will do), a  short length of dowel or similar, a small piece of WOVEN fibreglass cloth, 12 volt battery, disco fog fluid (available from Maplins), plastic or copper tubing for the flue to the funnel and a couple of screw block connectors.

To work out the length of the Ni-CH wire needs a bit of trial and error to get right, you need the wire long enough for the fog fluid to burn off but not get red hot.
Next, wrap the glass cloth around the dowel to act as a wick and spiral the Ni-CH wire around that making sure the wire doesn't overlap. Use the choc. block connectors to connect the power feed wires to the Ni-Ch wire (solder doesn't work for some reason) and place dowel at an angle in the reservoir with the wick in the fluid but not the element. Secure the computer chip fan to the reservoir. Fill  the reservoir with fluid up to the bottom of the element and connect up the power and switch on.
I have done a schematic drawing to try to explain how I did it, it's easier than it looks.

just popped on this topic after buying a ultrasonic humidifyer (getteng a problem with the heating ,too dry) ,now this thing kicks out loads of water vapour and as a thought could one be made for 12/24v to work on a steam boat or the like .
just an idea .

I think that's pretty much the idea that JJC had a few years ago.  It seems that there are inherent problems with consistent reliability.

Most oil based smokers can have a few drops of aromatherapy oil added.  You might get some funny looks at the lakeside, and a whole new bunch of friends.

thanks for all the help guys.

Hi Dan,
If you are burning oil maybe a little water or condensation has got in?.

Just bought the fogging liquid and a fan from Maplins,can't wait to get started on the DIY version!,what I thought I might do is fit a micro switch linked to the rudder at its furthest throw so that I can turn on the smoke at will.

Hi Len, I tried it on 6 volts with a shorter length of wire, it did work but not as well as it does on 12. The red and black wires are the ones to use on the fan.

Len

I suspect the yellow wire is a signal wire of some sort if it is a computer fan. Try just using the red and black. If it is a computer fan, its probably designed to run on 5volts.

The yellow wire is the speed sensor used to detect fan failure

Hi Guys,
Just made a smoke genorator from the plan above worked 1st time,well 2nd actually as the fan sucked instead of blew!.
If I want darker smoke, can I dye it with food dye?. I got the smoke liquid from Maplins.

Regards.

Dunno never tried it why not give it a go and see what happens :D :D :D Glad you got it working personally i think it chucks out just the right amount of smoke, the commercial units seem to produce too much smoke in my opinion, like a destroyer smokescreen!!

Hi everyone  Just thought I'd put my two peneth in, I got some pond vaporisers from Maplins. Run them on 24v and use a fan to blow mist up funnels. batteries last hours smoke very realistic even if it is water vapour. Several members of Barry model boat club have done the same. reliable and effective. When on offer have done it for as little as 6. all the best PIT

Gooday Pit have seen those vapourisers at Maplins and was wondering about them. Can you give some idea how to set them up in a hull. Do they only work on 24v ?
